"If the input voltage is too low, Q1 turns on and dumps the gate of Q3 to ground."
As Q3 is a p-channel mosfet, it will turn on in this case and there will be no undervoltage protection
I have another question regarding this circuit. If i want to change high side pmos switch to low side nmos switch what changes i hav to make in circuit and design?
